(1) After the first transporting device 10 transports the chassis assembly to the accommodating space 104, the lifting mechanism 11 may raise the chassis assembly, the first and second telescopic structures 103a and 103b protrude toward the accommodating space 104, and support the chassis assembly raised by the lifting mechanism 11;

(2) The assembly tool 102 grips the side wall assembly, the front wall assembly and the rear wall assembly transported by the second transporting device 20 and assists the operator in moving and assembling the side wall assembly, the front wall assembly and the rear wall assembly to the corresponding positions of the chassis assembly (after the assembly tool 102 grips the side wall assembly, the front wall assembly and the rear wall assembly by, for example, a gripper, the operator may perform a snap-fit for the mounting positions between the side wall assembly, the front wall assembly and the rear wall assembly and the chassis assembly, the assembly tool 102 may put down the gripper after the snap-fit is completed, return to perform a "gun-change" operation, and the operator may fasten the side wall assembly, the front wall assembly and the rear wall assembly to the chassis assembly after the snap-fit is completed);

(3) The assembly tool 102 grips the instrument desk assembly transported by the second transporting device 20 and assists the operator in moving and assembling the instrument desk assembly to the corresponding position of the chassis assembly;

(4) The assembly tool 102 grips the roof assembly transported by the second transporting device 20 and assists the operator in moving and assembling the roof assembly to the side wall assembly, the front wall assembly, and the rear wall assembly;

(5) The assembly tool 102 grips the wheel assembly transported by the second transport device 20 and assists the operator in moving and assembling the wheel assembly to the corresponding location of the chassis assembly.

According to the first embodiment of the present invention, the second transporting device 20 may also transport the interior and exterior trim assemblies from the material sorting area 200 to the vehicle body independent manufacturing island area 100, and the assembly tool 102 grips the interior and exterior trim assemblies transported by the second transporting device 20 and assists the operator in assembling the interior and exterior trim assemblies onto the corresponding positions of the vehicle body. The interior trim assembly may include a visor, a seat belt, an in-vehicle air circulation system, an in-vehicle lighting system, and the like. The exterior trim assembly may include a windshield (e.g., front windshield, rear windshield), a bumper (e.g., front bumper, rear bumper), an air intake grille, a rear view mirror, vehicle lights, a wiper, etc.

Mounting of the steering wheel assembly also typically requires mounting adjustment (e.g., position adjustment). Thus, according to the first embodiment of the present invention, the third transporting means may further transport the steering wheel assembly from the material sorting area 200 to the shutter assembly area 300, where the steering wheel assembly may be assembled to the corresponding position of the vehicle body in the shutter assembly area 300.

Referring to fig. 1 and 2, after the shutter assembly area 300 completes the vehicle assembly, oil filling (e.g., filling refrigerant, antifreeze, brake fluid, molten glass, etc.) may be performed in the oil filling/off-line filling area of the vehicle production line. As previously described, the shutter mounting area 300 may be disposed in the oil charging area. Then, the whole car can be started in a offline mode. If the whole vehicle is failed to start, the assembled vehicle is transported to a repairing area of a vehicle production line for problem investigation and repairing. After the whole vehicle is started successfully, the assembled vehicle is transported to a detection area of a vehicle production line to carry out various vehicle performance detection (such as electric detection, hub detection, intelligent calibration and the like). And if the performance of each vehicle is detected to be qualified, performing road test and rain test on the assembled vehicle. If the assembled vehicle passes the road test and the rain test, the assembled vehicle is transported to a commercial inspection area of a vehicle production line, and appearance detection is performed on the assembled vehicle to determine whether the appearance of the vehicle is defective (such as scratch and the like). If the assembled vehicle passes the business check, the vehicle may be put in storage awaiting shipment.

The vehicle production line according to the first embodiment of the invention may also assemble the vehicle body in the following modification. For example, the first transporter 10 carries an assembled body assembly into a vehicle body independent manufacturing island 100, and the lifting mechanism 11 of the first transporter 10 supports the body assembly for lifting (the support point may be a stringer location). After the vehicle body assembly is higher than the telescopic structure 103 of the fixed work table 101, the telescopic structure 103 protrudes toward the accommodation space 104. Next, the lifting mechanism 11 of the first transporting device 10 performs a lowering operation. By utilizing the width difference between the body skirt and the longitudinal beam, the telescopic structure 103 of the fixed working table 101 can smoothly support the body skirt. After completion of the vehicle body assembly landing, the first conveyor 10 may return to the material sorting area 200 to transport the chassis assembly to the vehicle body independent manufacturing island 100, or other first conveyors 10 may transport the chassis assembly from the material sorting area 200 to the vehicle body independent manufacturing island 100. The island region 100 is independently manufactured on the vehicle body, and can be visually identified through the positioning holes of the vehicle body assembly to perform lifting and assembling actions. In the process of assembly, operators can monitor and adjust the relation of the positioning pin holes. After completion of the associated pilot hole pin engagement, the automatic tightening machine may tighten bolts passing through the chassis assembly from below up to the respective vehicle body assembly, thereby securing the respective vehicle body assembly to the chassis assembly. After the chassis assembly and the body assembly are assembled, the assembly of the instrument desk assembly, the wheel assembly, the interior trim assembly, and the exterior trim assembly may be continued in the body independent manufacturing island 100 to be assembled as a body, similar to the vehicle production line according to the first embodiment of the present invention. In order to ensure convenient maintenance after the whole vehicle is sold, an up-down lap joint structure can be adopted, and a lifting automatic tightening machine is used for replacing high-station operation of the traditional production line.
